Improvement in lubricators for steam-engines



"To all whom it may concern aunt saw IMPROVEMENT IN LUBRIcA'roRs PenSTEAM-ENGINES.

0 The Schedule referred to in these Letters Patent and makifig p rt o heamfl- Be it known that I, G-nonen Grnrr, of Rainier, in the county ofColumbia, and State of Oregon, have invented a new and usefulImprovement in a Lubricating-Device for Steam-Cylinders; and I do herebydeclare that the following is 'a full, clear, and exact descriptionthereof, which will enable others skilled in the art to make and use thesame, reference being had to the accompanying drawing, formingpart ofthis specification, in which the drawing represents a vertical centralsection of my invention.

This invention relates to a new and improved device for lubricatingsteam-cylinders, and it consists of a-novel arrangement ofvalves',.oil-chamber, and lever, as hereinafter shown and described,whereby several advantages are obtained, as herein set forth.

A represents an oil-receiver, which "is provided with a pendent pipe, B,the latter extending down through a stufiing-box, G, into anoil-chamber, I);

This oil-chamber is screwed on the upper end of a pipe, E, the lower endof the latter being screwed into the steam-cylinder shown in red.

11 is a lever, formedwith a yoke, G,throughflwhich *the pipe B passes,the latter being secured in theyoke by a pin, a. v

The fulcrum b of the lever F is an arm, 0, attached tothe outer side ofthe'oil-chamber, and a springcatch, H, is-also attached to the exteriorof the oilchamber, to hold the lever F down when necessary.

. e I representsa valve, which is attached to the lower end of a stem,J, which. passes up, through the pipe E, into the oil-chamber I), andisconnected, by a coupling, d, with the stem K-of a valve, L.

When the lever F is held down by the spring-catch I H, the valve Lcloses the lower end of the pipe B, but

the valve I is open, so that any oil in D may descend through pipe Einto the cylinder.

Whenever it is necessary to replenish D with oil, the catch H is shovedto one side of the lever F, and the valve I is instantly raised andclosed under the pressure of the steam, and the lever F is then raised atrifle by hand, so that the pipe B will be raised from valve L, and thesteam in B at once escapes, and D supplied with oil, by pouringtthelatter into A.

By thus depressing lever F, and securing it by catch H, the pipe B isclosed on valveL, valve I opened, and oil from D allowed to pass intothe cylinder.

A stop or pin, e, which passes through the stem J, limits the descent ofthe valve 1.

The superiority of this invention consists in the fact that there are noplugs to get out of order, or injnred or cut'by sand, a contingency ofcommon occurrence with the ordinary lnbricators. The device may also .bemore readily supplied with oil than other devices for the same purpose.

Having thus described my invention,

I claim as new, and desire to secure by Letters Patent- The two valves LI, pipes B E, oil-chamber D, and lever F, all constructed and arrangedto operate in the manner substantially as and for the purpose set forth.GEORGE GIRTY. Witnesses:
